just a six is right,
The 250 points to HEI swap is easy. The distributor head is much larger than the old points distributor. I even managed to fit one on my 292 (see pic in recent post on "How headers should fit" by 66chevy truck). That is not as easy a swap. When you drop the HEI in a 292 you get about 40 degrees rotation. If you want to change the position any further then you must remove the distributor, reinstall it and reset the timing.
You don't have to worry about that on your 250.
